AI Technical Summary

Benefits of technology

[0010]The present invention is directed to an improved all terrain vehicle that has a chassis, front and rear wheels, an engine mounted in between the front and rear wheels, a seat to be occupied by a driver during use, and handlebars for enabling the user to steer the two front wheels.
[0011]The apparatus includes an inclined intake conduit that has a forward air intake opening and a housing air intake that communicates air from the forward air inlet to the transmission housing for cooling purposes. Air is discharged from the transmission housing via an air discharge passageway. Both the forward air intake passageway and the rear air discharge passageways that communicate with the transmission housing are preferably inclined. The intake opening and discharge opening are each at the highest possible location to lessen the chance that they will make contact with a body of water such as a stream, pond, lake, flooded field, marsh, swamp or with splashing water.

Problems solved by technology

When used in such an environment, these vehicles (particularly those with automatic transmissions) inadvertently intake water than can find its way to the transmission housing and / or the air filter housing.
In such a situation, the vehicle can become dangerous to operate and / or operable.

Embodiment Construction

[0018]FIGS. 1–4B show the preferred embodiment of the apparatus of the present invention, designated generally by the numeral 10 in FIG. 1. All terrain vehicle 10 has a chassis 11 to which is mounted two front wheels 12 that are steerable wheels 12 and a pair of rear wheels 13. A seat 14 is positioned generally in between the front 12 and rear 13 wheels.

[0019]Handlebars 15 are mounted in front of seat 14 and enable an operator to steer the vehicle 10. An engine 16 is provided in between the front 12 and rear wheels 13 and generally below the seat 14. A transmission housing 17 is provided with a known automatic transmission that transfers power from engine 16 to rear wheels 13.

[0020]Transmission housing 17 has interior 18. The known transmission includes pulleys and a belt 21 or belts. The pulleys can include forward pulley 19 and a rear pulley 20 as shown in FIGS. 1 and 5. Belt 21 connects pulleys 19, 20.

[0021]Transmission housing 17 interior 18 receives cooling air from lower air i...

Abstract

A method and apparatus for continuously discharging inadvertently accumulated water from the automatic transmission housing and/or air filter housing of an all terrain vehicle is disclosed. The continuous water discharge system employs a one-way valve structure that is mounted at the lower end portion of either or both of the automatic transmission housing and air filter housing.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Priority of U.S. Provisional Patent Application Ser. No. 60 / 400,496, filed Aug. 1, 2002, incorporated herein by reference, is hereby claimed.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicableREFERENCE TO A “MICROFICHE APPENDIX”[0003]Not applicableBACKGROUND OF THE INVENTION[0004]1. Field of the Invention[0005]The present invention relates to all terrain vehicles. The present invention more particularly relates to an improved all terrain vehicle that can automatically eliminate water that might accumulate in the air filter housing or transmission housing when the vehicle is used in inundated areas.[0006]2. General Background of the Invention[0007]All terrain vehicles are used in many different types of terrain. Some of these vehicles are subjected to use in inundated areas such as rice fields, marshes, swamps, streams, river bottoms and the like. When used in such an environment, these vehicles (particularl...
